Halo

    Halo: Combat Evolved was the first halo made, or Halo 1 as most know it as.  This is the game that started the series off to the point it has came to.  This game was based on Master Chief, a spartan warrior who was trained from birth to become an elite soldier in the UNSC against the covenant.  The covenant is an alien race that consists of elites, grunts, hunters, jackyls, and brutes.  These are forces you fight against throughtout the game and the entire series as well.
